Existing code should see no change in performance from the previous PHP 5.3 alpha, and a significant improvement from PHP 5.2. In fact, code that uses a lot of static method calls or class constants might see a slight (imperceptible) performance increase, as a few hash lookups would be removed. I have not benchmarked this.
